I don’t know where to put this one but didn’t find anything when I searched for it so here goes.
In gmail there is a free phone call feature where you call someone from your computer. Free long distance in North America and I’ve been using it for that in Chromium (Kubuntu) for some time.
Under Brave it says “Call phones feature is not available” but if you turn Brave “Shields Down” then it works. Just thought I’d toss that out there in case anyone else encounters it.
